tion, strong, durable, eilicient in operation and which may be manufactured at lowcost.

All of the foregoing and-'still further objects andadvautafges ofthe inventioumay become apparent `from a study of the following specification, taken in connection with the accompanying Vdrawings whereinV like characters of reference designate corresponding parts throughout the several views,v and wherein i 1 Figure 1 is a view in top planshowing a shuttle and portions of a shuttle box equipped with an electric filling feeler in accordance with this invention. Y

Figure 2 is a view. principally in top plan alud partly broken away in section of the shutt e. Y v

Figure 3 isa cross sectional view taken substantially on the line 3-3 of Figure 2 looking in the direction indicated by the arrows.

Figure 4 is a diagrammatic view showing the electric circuit and the contacts.

Figure 5 i-s a view in side elevation of the shuttle showing the Contact plates mounted thereon.

lFigure 6 is a top plan view of a shuttle showing a slightly modified form of the invention. Y

Figure 7 is a fragmentary view partly in longitudinal section and taken substantially on the line 7 7 of Figure 6. Y

Figure `8 is a diagrammatic view of the electric circuit embodied in the modified form of invention illustrated-in 4`6 .l

and 7. Referring to the drawings in'detail,l it will `be seen that the reference numeral 1 designates a shuttle adapted-for reception between the box platesl 2 and .3 of a loom (not shown). A spindle .4 ismounted for swinging movement in the usual manner Vin the shuttle 1 Vou the transverse pin 5 and the usual fiat,

metallic spring 6 is secured on one end por- '65 tion :of the shuttle 1 by the screw 71and is engaged ywith the pivoted-end portion .of the spindle 4`or yieldingly retainingsa-id spin-Y f dle in operative position in'theshuttle." A

filling carrier such as a'cop, quill, tube, spool 30 i or the like 8 is removably mounted on the Y spindle 1 and has mounted on one-.end the metallic ferrule 'or tubular contact member-9. A flange 10 is'formed integrally 'ony one end of the tubular 'contact 9 for engagement by i the resilient metallic retaining ngers '11 which releasably retain the cop or the like 8 in position on the spindle 4.

Mounted 'u the shuttle 1 adjacent the tubular contact `9 is an .angular metallic bracket W0 12 (see Figure 3) 'from which ythe resilient metallicv feeler lingers k13 .extend for electric engagement with the tubular contact 9 when Vthe thread .or yarn is nearly exhausted from the cop or the like S. v A pair of longitudinally "'15 spaced elongated contact plates 14 and 15 are countersunk in the outer side wall of the shuttle 1 which is adjacent'the box plate 3, said contact plates being secured in any suitable manner, as by the screws 16. The con-"i0 tact plate 14 is electrically connected with the metallic bracket 12 by the conductor wire 17 `which passes through the side wall oit-the shuttle 1 for engagement with said` contact plate 14. A current conductingy wire 18 has one end connected 'with the pivot pin 5 and its other end .extending through the side Wall of the shuttle 1 and connected to the .contact plate 15. A coiled spring 19 encircles the spindle .4 and'is engaged withthe oop .8 in 90
